Do you know?

  • 1. How many miles of municipal stormwater pipes

are you responsible for?

  • 2. How many stormwater outfalls does your

municipality own?

  • 3. What waterbodies does your town drain to and

are they polluted?

  • 4. Does your town/city owns any swirl separators

(e.g. Stormceptors), detention basins or bioretention systems, and where they are?

  • 5. Bonus: What does MS4 stand for?

The Problem: Rain is clean… until it’s not. Stormwater carries pollutants to our waters.

We Take Care of Problems We Can See….

MVPC Good Housekeeping Survey:

  • 7 of 10 DPWs manage their maintenance schedules in

response to citizen complaints

  • 3 of 10 have a written annual maintenance schedule

Regulations: These Affect Your Stormwater O&M Responsibilities

  • NPDES MS4 General

Permit

  • State Wetlands

Protection Regulations

  • State Stormwater

Management Manual

  • Local Wetlands Protection Regulations
  • Local Stormwater Management Regulations
  • Local Zoning Code + Subdivision Regulations
slide-21
SLIDE 21

Regulations – Local Boards + Commissions

  • Regulations affecting municipal stormwater

infrastructure:

– NPDES MS4 General Permit – State Wetlands Protection Regulations

  • State Stormwater Management Manual

– Local Wetlands Protection Regulations – Local Stormwater Management Regulations – Local Zoning Code + Subdivision Regulations

– Other: drinking water source protection, contaminated soils regulation

Decisions by local boards/commissions

slide-22
SLIDE 22

Local Stormwater Regulation - Applicability

Wetlands Protection Regulations Stormwater Regulations Any impervious cover within: 100’ of a wetland, or 200’ of a stream/river Projects > 1 acre, including road projects Large projects and subdivisions

slide-23
SLIDE 23

Wetlands Protection Regulations

  • State and Local Wetlands Protection

Regulations

– Regulate stormwater management for projects within 100 feet of a wetland, 200 feet

  • f a stream or river

– MA Stormwater Handbook

  • Defines the menu of treatment practices
  • Treatment (sizing and design) standards
  • Requires a written O & M Plan
slide-24
SLIDE 24

Local Stormwater Management Regulations

  • Required by existing 2003 NPDES MS4

Permit

  • Some use the MA Stormwater Handbook
  • Implementing agencies vary among

towns:

– Planning Board – Conservation Commission – Zoning Board – DPW

slide-25
SLIDE 25

Local Zoning and Subdivision Regulations

  • Usually have ‘drainage’ requirements
  • Often predate the MA Stormwater Manual
  • Stormwater standards often too general or

poorly written to apply effectively

  • Sometimes conflict with other requirements
  • Implemented by:

– Planning Board, Zoning Board

slide-26
SLIDE 26

NPDES MS4 General Permit

  • Federal Clean Water Act program
  • Permit-holder: Local municipality for its MS4

(MS4: municipal separate stormwater sewer system)

  • Goal: Reduce pollutants in local water
slide-27
SLIDE 27

NPDES MS4 General Permit Overview of Requirements

Stormwater Management Plan:

  • Water Quality Based Effluent Limitations
  • Discharges to Certain Impaired Waters
  • Reduce Pollutants to the Max Extent Practicable

(MEP)

– Public education and outreach – Public involvements and participation – Illicit discharge detection and elimination program – Construction site stormwater runoff control – Stormwater management in new dev’t and redev’t – Good housekeeping and pollution prevention

NPDES MS4 General Permit Minimum Control Measures

  • 1. Public Education & Outreach
  • 2. Public Involvement &

Participation

  • 3. Illicit Discharge Detection and

Elimination

  • 4. Construction Runoff
  • 5. Post-Construction Stormwater

Management

  • 6. Pollution Prevention & Good

Housekeeping in Municipal Operations

slide-29
SLIDE 29

What is Municipal Pollution Prevention/ Good Housekeeping? Our working definition:

  • Assessment and subsequent

alteration of municipal operations to reduce the amount of pollution entering the storm drain system and, eventually, receiving water through the implementation of Best Management Practices (BMPs)

slide-30
SLIDE 30

Good Housekeeping Requirements ‘Infrastructure Operations and Maintenance’

(Permit section 2.3.7.a.iii)

  • Establish a written maintenance program (Yr 1)
  • Catch basin cleaning must be optimized:
  • Prioritize inspections near

construction activities, clean more frequently if needed

  • Clean catch basins before they reach

50% full

  • Plan and tracking for optimizing catch

basin cleaning throughout the system

  • Annual Reporting: # CBs, #

inspected, # cleaned, volume or mass of material removed 50% Full

slide-31
SLIDE 31
  • Sweeping of Roads and Parking Lots

– Minimum 1/year in the spring – More frequent sweeping in targeted areas (determined by the municipality based on catch basin inspections and cleaning) – Rural uncurbed roads with no catch basins

  • Minimum 1/year in the spring, or
  • Develop an inspection, documentation and targeted

sweeping plan (Yr 1)

  • Catch Basin Cleanings and Street Sweepings

– Ensure proper storage of cleanings and sweepings prior to disposal

Good Housekeeping Requirements ‘Infrastructure Operations and Maintenance’

(Permit section 2.3.7.a.iii)

slide-32
SLIDE 32
  • Winter Road Maintenance

– Establish procedures for winter road maintenance (Yr 1) – Minimize use of sodium chloride, other salts – Evaluate opportunities for alternatives

  • Storm Drain Systems and Stormwater

Treatment Structures

– Establish inspection and maintenance frequencies and procedures – Inspections 1/year

Good Housekeeping Requirements ‘Infrastructure Operations and Maintenance’

(Permit section 2.3.7.a.iii)

slide-33
SLIDE 33

Enhanced Requirements for Discharges to Impaired Waterbody

slide-34
SLIDE 34

Enhanced Requirements for Discharges to Impaired Waterbody Nitrogen/Phosphorus Impairment:

– Street and parking lot sweeping 2/yr

Chloride Impairment:

– Salt reduction plan developed (Yr 3) and implemented (Yr 5)

Solid, Oil/Grease or Metals Impairment:

– Street and parking lot sweeping increased to target high pollutant sources – Increase catch basin inspections
